How to simultaneously read audio samples while recording in python for real-time speech to text conversion?

和自甴很熟 提交于 2020-05-12 09:08:51
问题 Basically I have trained a few models using keras to do isolated word recognition. Currently i can record the audio using sound device record function for a pre-fixed duration and save the audio file as a wav file. I have implemented silence detection to trim out unwanted samples. But this is all working after the whole recording is complete. I would like to get the trimmed audio segments immediately while recording simultaneously so that i can do speech recognition in real-time. I'm using

Waiting for thread while updating Swing

问题 I have problem with handling threads in my application. It creates JFrame and starts a new Thread. Last one will execute external application and update GUI. Then I have problem to make Main class to wait for second thread to finish, but also to update GUI simultaneously. Here's my example (shortened): class Main { public int status; public Main() { // Creating GUI etc. SwingUtilities.invokeLater(new Runnable() { public void run() { JDialog id = new JDialog(); id.button.addMouseListener(new

How to configure RTEMS in Eclipse?

让人想犯罪 __ 提交于 2020-04-30 07:01:23
问题 I want to develop a simple program using RTEMS in Eclipse using Ubuntu. I have installed RTEMS CDT Support following https://devel.rtems.org/wiki/Developer/Eclipse/Plugin But I can't configure Window > Preferences > C/C++ > RTEMS paths, because /opt/rtems-4-9 (default value) doesn't exist. When I've tried to use RTEMS Toolchain in a new project, next message is shown: *'Invoking: RTEMS C++ Compiler /opt/rtems-4.9/bin/g++ -O0 -g -Wall -c -fmessage-length=0 -pipe -MMD -P -MP -MF"src/HelloWorld

Is there any alternative to the websockets for using in shared hosting

问题 Is there any alternative for the websockets to use in shared hosting? I know about node.js, socket.io, Express.js but Can't use them in shared hosting. So, if there is any alternative used for making a realtime website then tell me. 回答1: If your shared hosting provides PHP support, you can use one of the WebSockets libraries in PHP: Ratchet phpwebsocket PHP-WebSockets For installing Ratchet, read my answer on how to install Composer on a shared hosting. Alternatively, you can install Node.js

Estimating of interrupt latency on the x86 CPUs

好久不见. 提交于 2020-02-17 13:53:22
问题 I looking for the info that can help in estimating interrupt latencies on x86 CPUs. The very usefull paper was found at "datasheets.chipdb.org/Intel/x86/386/technote/2153.pdf". But this paper opened a very important question for me: how can be defined the delay provided by waiting of completion of the current instruction? I mean delay between recognition of the INTR signal and executing of INTR micro-code. As I remember, the Intel Software developer manual also tells something about waiting

How to dynamically render/load pages in express?

走远了吗. 提交于 2020-01-31 13:26:27
问题 I need to dynamically load/render part of a page in nodejs (v1.8.15) with express (>3.0) framework. Generally, I want to create a single-page app. I have a menu at the top of the page with links. Clicking on the links will change the content below, as in AJAX page loading. For example: >home|login|signup|chat ..content for home.. If I press the 'signup' link: home|login|>signup|chat ..content for signup.. In express I have routes on the server: var express = require('express'); var app =

What makes Erlang suitable for soft real-time applications?

我只是一个虾纸丫 提交于 2020-01-31 04:58:39
问题 Some background I'm working on building a programming language for digital media programming, which should support concurrency using no-sharing message passing and soft real-time (i.e. do your best to compute audio/video without losing samples or frames and with a constant throughput). It turns out that both these features are surprisingly difficult to combine, mainly because of one particular constraint: real-time code should not dynamically allocate memory. My language should make it easy

Latency in ioread

青春壹個敷衍的年華 提交于 2020-01-25 04:42:07
问题 Suppose you have a PCIE device presenting a single BAR and one DMA area declared with pci_alloc_consistent(..). The BAR's flags indicate non-prefetchable, non-cacheable, memory region. What are the principle causes for latency in reading the DMA area, and similarly, what are the causes of latency reading the BAR? Thank you for answering this simple question :D! 回答1: This smells a bit like homework but I suspect the concepts are not well understood by many so I'll add an answer. The best way

Get Jupyter notebook to display matplotlib figures in real-time

纵然是瞬间 提交于 2020-01-23 06:12:50
问题 I have a long running Python loop (used for machine learning), which periodically prints output and displays figures (using matplotlib). When run in Jupyter Notebook, all the text (stdout) is displayed in real-time, but the figures are all queued and not displayed until the entire loop is done. I'd like to see the figures in real-time, on each iteration of the loop. During cell execution, not when the entire cell execution is done. For example, if my code is: for i in range(10): print(i) show
